Method for Assistance with the Remote Configuration of an Euicc Card and System for Implementing Such a Method

1. A remotely configurable smart card, called an embedded universal integrated circuit card (eUICC) card, to be non-removably integrated into a terminal storing a provisioning profile comprising data used by said terminal to communicate with a provisioning network of a first wireless communication system to configure an operation profile on the eUICC card, the operational profile comprising data relating to a subscription of the terminal with an operator of an operational network of the first wireless communication system, wherein: the provisioning profile is incomplete, in that one or more missing data essential to establish a communication between the terminal and the provisioning network are not defined by default in the provisioning profile; the eUICC card comprises an assistance profile comprising applications and data allowing the terminal to access an assistance network of a second wireless communication system, the second wireless communication system being distinct from the first wireless communication system; and the eUICC card is configured to complete the provisioning profile with the missing data obtained by the terminal by establishing a prior communication with the assistance network.

2. The eUICC card according to claim 1 , wherein the missing data comprises at least one of the following elements: an indication that the provisioning profile is active; at least part of an international mobile subscriber identity (IMSI) of the provisioning profile with the provisioning network; an identifier of at least one of an authentication algorithm and an authentication key of the provisioning profile; and an identifier of a roaming network of the first wireless communication system linked to the provisioning network.

3. The eUICC card according to claim 1 , wherein the provisioning profile comprises a set of possible values preconfigured for at least one missing datum; and wherein an identifier of a value of said set is obtained through the prior communication established between the terminal and the assistance network.

4. The eUICC card according to claim 1 , wherein the eUICC card comprises incomplete provisioning profiles; and wherein the eUICC card is configured to determine an incomplete provisioning profile to be used to remotely configure the eUICC card from an identifier obtained through the prior communication established between the terminal and the assistance network.

5. A terminal comprising the eUICC card according to claim 1 .

6. The terminal according to claim 5 , wherein the terminal is configured to determine an information on a current geographical position of the terminal and to transmit the information on the current geographical position to the assistance network through the prior communication.

7. An assistance network for a terminal according to claim 5 , the assistance network being linked to a subscription management entity and comprising a server configured to: receive a request from the terminal to obtain the data missing from the incomplete provisioning profile; transmit the request to the subscription management entity; and transmit to the terminal the data missing from the incomplete provisioning profile.

8. The assistance network according to claim 7 , wherein the assistance network is configured to provide an information on a current geographical position of the terminal to the subscription management entity.

9. The assistance network according to claim 7 , wherein the assistance network is a low power wide area wireless communication network.

10. A subscription management entity of an eUICC card of a terminal according to claim 5 , the subscription management entity being linked to an assistance network and comprising a server configured to receive a request from the terminal to obtain the data missing from the incomplete provisioning profile, to transmit the request to the subscription management entity, and to transmit to the terminal the data missing from the incomplete provisioning profile; and wherein the subscription management entity is configured to receive from the assistance network a request for the data missing from the incomplete provisioning profile of the terminal, and to transmit to the assistance network the data missing from the incomplete provisioning profile.

11. The subscription management entity according to claim 10 , wherein the subscription management entity is configured to determine at least one of the data missing from an incomplete provisioning profile of the eUICC card of the terminal according to an information on a current geographical position of the terminal.

12. A system comprising the subscription management entity according to claim 10 , at least one terminal, a first wireless communication system and a second wireless communication system distinct from the first wireless communication system; and wherein the second wireless communication system comprises the assistance network.

13. A method for assistance with a remote configuration of an eUICC card of a terminal, implemented by the system according to claim 12 , and comprising: transmitting a request by the terminal on the assistance network of the second wireless communication system to complete a provisioning profile of the eUICC card; obtaining information missing from the provisioning profile by the assistance network from the subscription management entity; transmitting the obtained information to the terminal on the assistance network; updating the provisioning profile with the obtained information by the eUICC card; and remotely configuring the eUICC card through the provisioning network of the first wireless communication system using the updated provisioning profile.

14. The method according to claim 13 , wherein at least part of the information obtained by the assistance network from the subscription management entity is defined according to an information on a current geographical position of the terminal.
